First, explanation is installed a pair of buffer unit 5,5 in the bolt shaft 71 of the tight part 7 of pincers opposed to each other via slip guiding element 4, in flexible adjustment, the formation of the one party butt of the one party of this two buffer unit 5,5 and opposed check plate 32,32 (Fig. 5 reference).
When flexible adjustment, first via slip guiding element 4 be installed on the tight part 7 of described pincers bolt shaft 71 buffer unit 5 will with certain butt of opposed a pair of check plate 32,32 to buffer unit 5, move (Fig. 5 (A) with reference to).Check plate 32 with the moment of buffer unit 5 butts and after a while, the drift angle 52t part elastic deformation of the protuberant bar 52 of buffer unit 5 (Fig. 5 (B), (C) with reference to).And the drift angle 52t part of elastic deformation at once elasticity of form is replied, protuberant bar 52,52 ... become line contact (Fig. 5 (D) reference) with contacting of check plate 32.
Thereby, when flexible adjustment, even if making its flexible setting range is maximum adjustment, make buffer unit 5 and check plate 32, be the state of butt chronically, the also not strongly crimping of buffer unit 5 and check plate 32 plates.And, again stretch while adjusting, even if buffer unit 5 and check plate 32 crimping, both are with the crimping of line contact condition, so the engaging force based on this crimping very a little less than, can easily peel off, and can prevent that buffer unit 5 is from peeling off and come off with the installing condition of slip guiding element 4.
And then, the protuberant bar 52 of buffer unit 5 forms section triangle shape, drift angle 52t(bight as this protuberant bar 32) if top end part when flexible adjustment and check plate 32 butts, in this moment, so the little and wall thickness of volume is carried out elastic deformation (Fig. 5 (B) with reference to) easily near drift angle 52t.Thereby, buffer unit 5 just with check plate 32 butts after, from counter-force q, the q of drift angle 52t part ... also little (Fig. 5 (B) with reference to), elastic deformation easily, impact-absorbing, and impulsive sound almost can be eliminated or reduced.
And then, protuberant bar 52 just with the butt of check plate 32 after, drift angle 52t part is elastic deformation as previously mentioned, but the elastic deformation of drift angle 52t part is large, the volume of drift angle 52t part also becomes also thickening (Fig. 5 (C) with reference to) gradually of large and wall thickness.
Thereby at protuberant bar 52 to the moment of the butt of check plate 32 and after a while, it is large and based on elastomeric counter-force q, q that elastic deformation amount also little by little becomes ... also rise (Fig. 5 (C) reference), this can play the effect of the damper element in damping of shocks well.In addition, even if by buffer unit 5 butt with check plate 32, the drift angle 52t part elastic deformation of buffer unit 5, recovery of shape at once after butt, check plate 32 moves a little and stops (Fig. 5 (D) with reference to) simultaneously.Utilize these stroke, when flexible adjustment, the operation feeling in the time of can making buffer unit 5 stop with check plate 32 butts is very good.
The protuberant bar 52,52 of buffer unit 5 then, is described ... butt stroke in the embodiment of the formation that outstanding size is separately different (Fig. 6 (A) to (D) with reference to).When flexible adjustment, check plate 32 starts to move closer to (Fig. 6 (A) reference) to buffer unit 5.Then, primitively the drift angle 52t of the protuberant bar 52 of overhang maximum and check plate 32 butts.Now, the protuberant bar 52 that overhang is little also not with check plate 32 butts.
At this, and the protuberant bar 52 of check plate 32 butts and the poor Δ t of generation time between the protuberant bar 52 of butt (Fig. 6 (B) with reference to) not also.And, the poor Δ t of interval time, other protuberant bar 52 and check plate 32 butts, as previously mentioned, the drift angle 52t of protuberant bar 52 part is elastic deformation on one side, whole protuberant bars 52,52 ... become butt state (Fig. 6 (C) reference) on one side with check plate 32.And, even if the drift angle 52t part elastic deformation of buffer unit 5, recovery of shape after butt just, check plate 32 moves a little and stops (Fig. 6 (D) with reference to) simultaneously.
Thus, can the stage ground impact-absorbing and relax impact.And, at the protuberant bar 52,52 of buffer unit 5 ... with the protuberant bar 52,52 of buffer unit 5 at once after the butt of check plate 32 ... elastic recovery.Now, the protuberant bar 52,52 of reply ... the protuberant bar of existence and check plate 32 butts and the not protuberant bar of butt, its gap is Δ d, the protuberant bar 52 of overhang maximum and check plate 32 butts.Thereby buffer unit 5 contacts only one with the line of check plate 32, make protuberant bar 52 little with the crimp force of check plate 32, can further prevent that buffer unit 5 from coming off from bolt shaft 71.
In addition, making a plurality of protuberant bar 52,52 of buffer unit 5 ... the embodiment (Fig. 3 (B) with reference to) of the different formation of the angle of each drift angle 52t in, each protuberant bar 52,52 ... the volume of drift angle 52t part on top and the difference such as wall thickness.Thereby, can make each protuberant bar 52,52 ... drift angle 52t part elasticity intensity of force, easily produce elastic deformation degree different.Thereby according to the weight of support tube 1, other the difference of weight etc. of parts, impact during flexible adjustment is also different, but can be involutory with the size of such impact.
Then, illustrate that a pair of buffer unit 5,5 is installed on check plate 32,32, when flexible adjustment, clamps the situation of the formation of the bolt shaft 71 of tight part 7 and the one party butt of two buffer units 5,5.At this, on check plate 32, form and be fitted slot part 32a, be the chimeric position of neck 53 of buffer unit 5.
And then the Width two ends of two retention tab 55,55 clamping check plates 32 of buffer unit 5, can be for stablizing buffer unit 5 and be installed on securely the state of check plate 32.And, during flexible adjustment, the direction of principal axis of bolt shaft 71 and each protuberant bar 52,52 ... continuous direction (long side direction) consistent (Fig. 9 (A) with reference to).
And, by the opposed dip plane 52a of protuberant bar 52,52 of adjacency in above-below direction, the groove of 52a Formation cross-section triangle.The circumferential lateral surface of bolt shaft 71 enters the part of this two dip plane 52a, the formed groove shape of 52a.State is now following state: the circumferential lateral surface of bolt shaft 71 with respect to the circumferential lateral surface of two dip plane 52a of the protuberant bar 52,52 of adjacency along the vertical direction, 52a along continuous straight runs butt, bolt shaft 71 by two dip plane 52a, 52a skewed clamp (Fig. 9 (B) with reference to).
Thereby, impact when bolt shaft 71 and buffer unit 5 butt alleviates, and bolt shaft 71 can not arrive the bottom by the groove of two dip plane 52a of the protuberant bar 52,52 of adjacency along the vertical direction, section triangle shape that 52a forms, with respect to two dip plane, is the only contact of line contact.Therefore, even if be chronically the circumferential lateral surface of bolt shaft 71 and the state of buffer unit 5 butts, can crimping yet, again stretching while adjusting, can prevent that buffer unit 5 from coming off from check plate 32.
In addition, as shown in Fig. 8 and Fig. 9, the axle collar 71a of the drum that forms this bolt shaft 71 is installed in bolt shaft 71 sometimes.Now, axle collar 71a as the circumferential lateral surface of bolt shaft 71 and with buffer unit 5 butts.
